USB-C (using the USB 3.1 bus) to VGA to connect external monitors, projectors, TVs, etc. VGA transmits video signal. Supports output up to 1920×1080 (1080p), with flexible support for USB 5G and DisplayPort 1.2 (DP Altmode). Supports VGA with bandwidth of 2.7 Gbps (HBR) and 1.62 Gbps (RBR) per lane.
USB port to connect external peripherals. Connects a USB cable (USB 3.0, 2.0, 1.1) to your computer with USB-C port. Delivers 3A max. power to attached devices with 5 Gbps max. transfer rate. Compatible to all Macs or PCs with USB-C port. USB-C port only for PowerDelivery.
Important Notice: Unplugging the power delivery (PD) from an external power adapter via the LMP USB-C Multiport Adapter can cause the sudden interruption of the power supplied to attached devices (i.e. an external USB HDD). This in return causes attached devices to be unmounted or to loose the connection shortly (the connection is re-established automatically after 2-3 seconds), which may bring about a loss of unsaved data. Therefore, we strongly advise to save all data and/or unmount any attached device before unplugging the PD!
Note: Not compatible with Apple USB SuperDrive
It is normal that any USB-C hub or dock becomes hot when attached to the laptop. The aluminum housing is meant to dissipate the heat from the inside to the environment. There is a number of chipsets working on the inside which are producing some heat since they are constantly in a stand-by position to react quickly should any port be used. The surface temperature is well within the allowed limits and reaches about 40° C in stand-by mode, 43° C under normal use and a max. of 48° C when all ports are in full use, CPU load at 100% and PD attached. The heat does neither pose a danger to the laptop or any attached device, nor does it influence the USB-C hub’s/dock’s performance or even shorten the life-span.
Furthermore, the surface appears to be hotter than it actually is since it is touched with the very senstive fingertips. We suggest to remove the USB-C hub/dock when not needed in order not to emitt unnecessary heat to the environment and not to use any energy.
Basically, you can use only the iMac (27-inch, Late 2009) and iMac (27-inch, Mid 2010) with a Mini-DisplayPort connection with the current Mac with Thunderbolt 3 (USB-C) ports. You need a USB-C to Mini-DisplayPort adapter (e.g. 16134/16138, LMP USB-C to Mini-DisplayPort adapter) or a USB-C dock with Mini-DisplayPort port (e.g. 18641/18645/19009, LMP USB-C Travel Dock 4K 9 Port or 17113/17278/18954, LMP USB-C Compact Dock 4K 8 Port or 17116, LMP USB-C Display Dock 4K 10 Port). Then a Mini-DisplayPort to Mini-DisplayPort cable (8305, LMP Mini-DisplayPort to Mini-DisplayPort cable) must be attached to the dock and the iMac.
With iMac (Mid 2011 to Mid 2014), it is possible to use the iMac as monitor with a Thunderbolt connection only. With a newer iMac, a Target Mode with an iMac is not possible anymore.
